COMPANY, OF NEW HAVEN, CONNECTICUT LOCK STRIKE Application filedFebruary 24, 1928. Serial No. 256,620.

This invention relates to a lock strike, and more particularly to animproved form of lock strike and improved manner of securing the same tothe jamb of a door or the like.

The lock strike of this invention, while not limited to use with aspring latch or lock to be mounted on an outer surface of a door, isespecially useful in connection with such a form of lock. According tothe prior art, the usual lock strike used in connection with a lock ofthis type is provided with a bolt-receiving body which is mortised intoan outer face of a door jamb or the like, and is provided with alaterally extending flange or other portion which is mortised into aninner face of the door casing. Such strikes are usually secured to thedoor casing by means of screws which pass from the exterior of thestrike through openings in the body thereof and into the door casings.In order to provide room for passing the screw or screws through thebody of the strike, the usual strike is provided with a much largerportion engaging the outer face of the door jamb than would otherwise benecessary and requiring, in most instances, that this portion bemortised into the j amb.

In order to provide a lock strike having a more sightly appearance thanthe usual strike, it is proposed in the present invention to provide astrike which may be mounted on the j amb of the door without the use ofexposed fastening means.

Another object of the invention is to provide a form of lock strikewhich may be mounted on the jamb of a door or the like without thenecessity of mortising the strike into the jamb or other support.

A further object of the invention is to provide a lock strike in whichthere is provided a concealed but eflicient means for securing thestrike to the jamb of the door.

To these and other ends, the invention conslsts 1n the novel featuresand combination of parts to be hereinafter described and claimed.

In the drawings,

Fig. 1 is a fragmentary view of a door and a door casing showing apreferred embodiment of my invention mounted thereon; Fig. 2 is a viewalongline 22 of Fig. 1;

Fig. 3 is a cross-sectionalview along line 3-3 of Fig.2; and

Fig. A isan end view of my improved lock strike, taken in a directionsimilar to Fig. 3.

Referring now to the drawings in which I have shown a preferredembodiment of my invention, the reference numeral 5 indicates in generala portion of a door having mounted thereon a lock casing 6, which may beof any usual or preferred type, and which will not therefore bedescribed herein in detail, the lock casing 6 being secured to the door5 by suitable means, as for example, screws 7, and being provided with alatch bolt 8, and the usual thumb turn 9 for retracting the bolt.

Adjacent the door dis a door jamb 10, having mounted thereon my improvedform of lock strike 11, which is provided with a bolt retractingface l2,and a bolt receiving opening 13. trike 11 is provided with a relativelynarrow face 14, which abuts against the outer face 15 of jamb 10, and arearwardly extending flange 16, which may be secured to the inner face17 of jamb 10 by suitable means, as, for example,screws 18. The side ofstrike 11 abutting against the face 15 of jamb 10 is preferably solidand passing from the interior of strike 11 through this solid portionand into jamb 10 is a suitable fastening meansherein shown inthe form ofscrew 19. As shown in the drawings, the face 14 is of less width thanthe depth of the bolt receiving opening 13 and the wall 20 of strike 11extends outwardly from jamb 10 substantially at an acute angle.

In use, my improved form of lock strike may be placed in a suitableposition on the jamb of a door opposite the lock with the face 14:abutting the outer face of the amb and the screw, or other fasteningmeans,

19 passed through the opening in the strike body provided for thatpurposes and into the jamb. It will be seen from Figure 1 of thedrawings that the screw 19 is entirely concealed when the door isclosed. By eX- tending wall 20 in a direction substantially forming anacute angle with the face of the door .jamb, it is possible to mount thestrike on the edge portion of the jamb where it Will not interfere withany beading, molding, or other ornamental portion of the j amb, while atthe same time the face 14 forms a suitable support for the strike.

By providing the lock strike with a solid portion at the back of thebolt opening and. a

passing a fastening member through this portion into the face of thedoor jamb, I am enabled to omit the laterally extending flange usuallyprovided at the face of the door jamb through which the fasteningmembers are ordinarily passed. This flange must be mortised into theface of the door jamb and by omitting that element I provide a lockstrike which may be secured in place much more easily, and at the sametime will not deface the door j amb.

While I have shown a preferred embodiment of my invention, it is to beunderstood that the same is not to be, limited to all the jamb abuttingface thereof and into the jamb of the door.

3. A look strike adapted to be applied to a door jamb comprising aninner face portion abutting against and secured to the door jamb and anouter wall substantially parallel to said inner face portion and ofgreater width than said face portion, and a rear wall inclinedrearwardly and outwardly from the door jamb and connecting. said outerwall and face portion.

In witness whereof, I have hereunto set my hand this 2d day of February,1928.
